Quantifying the amount of physical rehabilitation received by individuals living with neurological conditions in the community: a scoping review.

BACKGROUND: Physical rehabilitation is often prescribed immediately following a neurological event or a neurological diagnosis. However, many individuals require physical rehabilitation after hospital discharge. The purpose of this scoping review was to determine the amount of physical rehabilitation that individuals living in the community with neurological conditions receive to understand current global practices and assess gaps in research and service use. METHODS: This scoping review included observational studies that 1) involved adults living with a neurological condition, and 2) quantified the amount of rehabilitation being received in the community or outpatient hospital setting. Only literature published in English was considered. MEDLINE, EMBASE, AMED, CINAHL, Cochrane Library, and PEDro databases were searched from inception. Two independent reviewers screened titles and abstracts, followed by full texts, and data extraction. Mean annual hours of rehabilitation was estimated based on the amount of rehabilitation reported in the included studies. RESULTS: Overall, 18 studies were included after screen 14,698 articles. The estimated mean annual hours of rehabilitation varied greatly (4.9 to 155.1 h), with individuals with spinal cord injury and stroke receiving the greatest number of hours. Participants typically received more physical therapy than occupational therapy (difference range: 1 to 22 h/year). Lastly, only one study included individuals with progressive neurological conditions, highlighting a research gap. DISCUSSION: The amount of rehabilitation received by individuals with neurological conditions living in the community varies greatly. With such a wide range of time spent in rehabilitation, it is likely that the amount of rehabilitation being received by most individuals in the community is insufficient to improve function and quality of life. Future work should identify the barriers to accessing rehabilitation resources in the community and how much rehabilitation is needed to observe functional improvements.

Physiotherapy students' perspectives on the use and implementation of exoskeletons as a rehabilitative technology in clinical settings.

PURPOSE: Wearable lower body robotic exoskeletons are an emerging technology used in gait rehabilitation to facilitate task-specific overground walking. Despite their proposed utility as a rehabilitation intervention, exoskeletons have not been widely implemented into clinical practice by physiotherapists. This study aims to inform future development of exoskeleton technology through the exploration of physiotherapy student perspectives on the use of the H2 robotic exoskeleton and the implementation of exoskeletons as a therapeutic technology in neurological gait rehabilitation. METHODS: A qualitative descriptive study, including fifteen physiotherapy students, was conducted using three equally sized focus groups. A collaborative data analysis process was employed using the DEPICT model. RESULTS: Five themes were identified during data analysis: developing evidence-informed practice, clinical considerations for exoskeleton use, resource demands, device-specific challenges for implementation, and future development. The results suggest there are several barriers limiting novel clinicians' future use of exoskeletons. CONCLUSION: This study highlights current challenges surrounding exoskeleton implementation into clinical practice and provides direction for future exoskeleton development.Implications for rehabilitationPhysiotherapy students view exoskeletons as a potentially valuable rehabilitation tool once perceived limitations are addressed.This study encourages collaboration between physiotherapists and biomedical engineers for future exoskeleton development.More research is needed to inform treatment parameters and appropriate client criteria to guide exoskeleton use for gait rehabilitation.

Study Paradigms and Principles Investigated in Motor Learning Research After Stroke: A Scoping Review.

OBJECTIVES: To (1) characterize study paradigms used to investigate motor learning (ML) poststroke and (2) summarize the effects of different ML principles in promoting skill acquisition and retention. Our secondary objective is to evaluate the clinical utility of ML principles on stroke rehabilitation. DATA SOURCES: Medline, Excerpta Medica Database, Allied and Complementary Medicine, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials were searched from inception on October 24, 2018 and repeated on June 23, 2020. Scopus was searched on January 24, 2019 and July 22, 2020 to identify additional studies. STUDY SELECTION: Our search included keywords and concepts to represent stroke and "motor learning. An iterative process was used to generate study selection criteria. Three authors independently completed title, abstract, and full-text screening. DATA EXTRACTION: Three reviewers independently completed data extraction. DATA SYNTHESIS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension guidelines for scoping reviews were used to guide our synthesis. Thirty-nine studies were included. Study designs were heterogeneous, including variability in tasks practiced, acquisition parameters, and retention intervals. ML principles investigated included practice complexity, feedback, motor imagery, mental practice, action observation, implicit and explicit information, aerobic exercise, and neurostimulation. An additional 2 patient-related factors that influence ML were included: stroke characteristics and sleep. Practice complexity, feedback, and mental practice/action observation most consistently promoted ML, while provision of explicit information and more severe strokes were detrimental to ML. Other factors (ie, sleep, practice structure, aerobic exercise, neurostimulation) had a less clear influence on learning. CONCLUSIONS: Improved consistency of reporting in ML studies is needed to improve study comparability and facilitate meta-analyses to better understand the influence of ML principles on learning poststroke. Knowledge of ML principles and patient-related factors that influence ML, with clinical judgment can guide neurologic rehabilitation delivery to improve patient motor outcomes.

Influence of Multiple Sclerosis on Spatiotemporal Gait Parameters: A Systematic Review and Meta-Regression.

OBJECTIVE: To quantify the effect of multiple sclerosis (MS) on spatiotemporal gait characteristics accounting for disability severity and fall classification. DATA SOURCES: MEDLINE (1946-August 2018), Allied and Complementary Medicine Database (1985-2018 August), and PsycINFO (1806-August 2018) were searched for terms on MS and gait. STUDY SELECTION: Dual independent screening was conducted to identify observational, cross-sectional studies that compared adults with MS grouped according to Expanded Disability Status Scale (EDSS) level or fall history, reported on spatiotemporal gait characteristics, and were published in English. The search retrieved 5891 results, of which 12 studies satisfied the inclusion criteria. DATA EXTRACTION: Two authors worked independently to extract and verify data on publication details, study methodology, participant characteristics, gait outcomes, conclusions, and limitations. Risk of bias was assessed using the QualSyst critical appraisal tool. A random-effects meta-regression and meta-analysis were conducted on pooled data. DATA SYNTHESIS: All studies received quality ratings of very good to excellent and collectively examined 1513 individuals with MS. With every 1-point increase in EDSS, significant changes (P<.05) were observed in gait speed (-0.12 m/s; 95% confidence interval (CI), 0.08-0.15), step length (-0.04 m; 95% CI, 0.03-0.05), step time (+0.04 seconds; 95% CI, 0.02-0.06), step time variability (+0.009 seconds; 95% CI, 0.003-0.016), stride time (+0.08 seconds; 95% CI, 0.03-0.12), cadence (-4.4 steps per minute; 95% CI, 2.3-6.4), stance phase duration (+0.8% gait cycle; 95% CI, 0.1-1.5), and double support time (+3.5% gait cycle; 95% CI, 1.5-5.4). Recent fallers exhibited an 18% (95% CI, 13%-23%) reduction in gait speed compared with nonfallers (P<.001). CONCLUSIONS: This review provides the most accurate reference values to-date that can be used to assess the effectiveness of MS gait training programs and therapeutic techniques for individuals who differ on disability severity and fall classification. Some gait adaptations could be part of adopting a more cautious gait strategy and should be factored into the design of future interventions.

Structuring community-based adapted dance programs for persons post-stroke: a qualitative study.

PURPOSE: Dance improves physical, psychosocial, and cognitive function, while increasing community participation among community-dwelling individuals post-stroke. Yet little is known about how to structure community-based dance classes to optimize benefits and participation. This study aims to gain stakeholders' perspectives about how to optimally structure community-based dance classes for individuals with chronic stroke. METHODS: A qualitative descriptive approach utilizing focus group methods was implemented. Two focus groups were undertaken with each of three stakeholder groups: persons post-stroke (n = 9), rehabilitation therapists (n = 6), and dance instructors (n = 8). Focus groups were audio-recorded and transcribed verbatim, providing the raw data. Analysis of the focus group transcripts were completed using the DEPICT model of collaborative qualitative analysis. RESULTS: This study identified three main themes/topics requiring consideration when structuring community-based dance programs: the environment, flow of the class, and qualities of the dance instructor. The study findings highlight that the pedagogical skills and teaching philosophy of the dance instructor are integral for a successful dance program, as the dance instructor directly mediates both the environment and flow of classes. CONCLUSION: Recommendations generated from our study can inform the development of community-based dance programs that are practical, optimize health benefits, and meet the needs and interests of people post-stroke.IMPLICATIONS FOR REHABILITATIONDance is an effective way to improve physical, psychosocial, and cognitive function for persons post-stroke while also promoting meaningful social relationships within the community.A dance instructor who is a skilled communicator and is willing to adapt to the needs of the class, is the most important factor for a successful dance class.Creating a safe and inviting environment for a dance program, includes both the physical and emotional aspects of environment facilitating individuals to create connections with others and feel more confident in themselves.The structure of a dance class, based on the abilities, interests, and goals of dancers, should include elements of predictability and variability to keep dancers progressing and motivated, and be two times a week for 3 months lasting 1-2 h.

The effect of bed rest on balance control in healthy adults: A systematic scoping review.

The objective of this study was to determine the effect of bed rest on balance control and the mechanisms responsible for these changes. Searches were conducted in six databases. Studies had to be conducted on healthy adults who were subjected to bed rest (≥5 days), with balance control measures obtained before and after bed rest in order to be included. Risk of bias was assessed using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. After screening 9,785 articles, 18 were included for qualitative synthesis. Fifteen studies found decrements in at least one balance control measure following bed rest, either compared to baseline or controls, with eight studies observing impairments in >50% of their balance control measures. Of the 14 studies that included an intervention, four (mechanical stimuli, lower-body negative pressure, and training targeting strength, balance and/or aerobic capacity) successfully offset the majority of balance control deficits and targeted the musculoskeletal and cardiovascular systems. The findings of this review support bed rest negatively affecting balance control in healthy individuals. In clinical populations, these deficits may be further accentuated due to various comorbidities that impact balance control systems. PROSPERO Registration: CRD42018098887.

Re-analysis of safety data supporting doxylamine use for nausea and vomiting of pregnancy.

Antihistamines are commonly used to treat nausea and vomiting of pregnancy (NVP). We re-analyzed the 24 primary studies cited in a 1997 meta-analysis that concluded antihistamine use for NVP was safe as they had been studied in more than 200,000 participating women and the pooled odds ratio for congenital malformations was 0.76 (95% confidence interval [CI]: 0.60-0.94). Our analysis of this meta-analysis showed that 139,414 women were included in 22 original studies involving antihistamines, 129,108 of which were in studies involving doxylamine. In these studies, 23,485 women were exposed to antihistamines, 14,624 of which were exposed to doxylamine. The summary relative risk (cohort studies) and odds ratio (case-control studies) for congenital malformations from antihistamine exposure were 1.09 (95% CI: 1.01-1.18) and 1.04 (95% CI: 0.91-1.19), and for doxylamine exposure, the summary relative risk and odds ratio were 0.94 (95% CI: 0.80-1.10) and 1.07 (95% CI: 0.93-1.23), respectively. Although not a new systematic review, our re-analysis demonstrates that the safety data for antihistamines, and doxylamine in particular, are based on many fewer than 200,000 participating women and exposures, and that doxylamine use is not associated with a decreased risk of malformations as previously reported.
